Dish/Stirling

Dish concentrators reach the top in concentration and temperature. All demonstrators and marketable concepts combine the paraboloidal, two-axis tracking concentrator with a Stirling engine in the focus, delivering 3 to 25 kW per unit. Peak efficiency is 30% and annual performance at high level. However the costs of the relatively small systems, together with operational reliability are to be optimized by introducing large production series with optimized quality and fabrication technologies.
